NEW QUESTION 6
In a vSphere 6.5 cluster, the administrator notices that it is possible to set a percentage in the DRS option, “Control CPU over-commitment in the cluster.”
Which is the purpose of this setting?

• A. It sets and enforces a maximum percentage of virtual machine CPU usage in GHz in comparison to physical CPU availability in GHz.
• B. It sets and enforces a maximum ratio in percentage between powered on virtual machine CPUs and available physical CPUs on hosts.
• C. It prevents the creation of any additional virtual machines in the cluster.
• D. It calculates the total shares assigned to all virtual machines in comparison to GHz of available physical CPU.

Answer: B

Explanation: https://blogs.vmware.com/vsphere/2021/10/whats-new-in-vsphere-6-5-host-resource-management-and-operation over-commitment: This is an option to enforce a maximum vCPU:pCPU ratios in the cluster. Once the cluster reaches this defined value, no additional VMs will be allowed to power on."

NEW QUESTION 7
A vSphere HA cluster with four hosts has admission control configured to tolerate one host failure. Which statement is true if a fifth host is added?

• A. CPU and Memory capacity will be set to 25%.
• B. CPU and Memory capacity will be set to 50%.
• C. CPU and Memory capacity will be set to 20%.
• D. CPU and Memory capacity will be set to 30%.

Answer: C

Explanation: Select the Percentage of Cluster Resources Reserved admission control policy. This policy offers the most flexibility in terms of host and virtual machine sizing. When configuring this policy, choose a percentage for CPU and memory that reflects the number of host failures you want to support. For example, if you want vSphere HA to set aside resources for two host failures and have ten hosts of equal capacity in the cluster, then specify 20%

• B. Nothin
• C. Everything has stayed the same.
• D. Both resource pools no longer exist and all virtual machines that resided in the resource pools now reside under the hosts in the cluster.
• E. Both resource pools exist, but all virtual machines that resided in the resource pools now reside under the hosts in the cluster.

NEW QUESTION 11
What new feature is introduced in NFS 4.1 on ESXi 6.5?

• A. Storage DRS
• B. KRB5i
• C. IPv6
• D. AUTH_SYS

Answer: C

NEW QUESTION 12
What counter should an administrator check to determine if a virtual machine is ballooning?

• A. swapinRate
• B. vmmemctl
• C. vmmemctltarget
• D. swapped

Answer: B

Explanation: Memory Ballooning is the memory reclamation technique used by hypervisor to reclaim the memory back from the virtual machine.
When ESXi host running low on physical memory, It uses ballooning driver (vmmemctl.sys) to determine the how much memory from virtual machines can be get back to prevent the hypervisor swapping.

NEW QUESTION 13

An administrator has multiple vCenter Server 6.5 systems but cannot enable Storage I/O Control (SIOC) on a datastore shared by ESXi hosts managed by the vCenter Server systems.
Which action should the administrator take to resolve the issue?

• A. Unmount the datastore and then enable SIOC on the vCenter Server system.
• B. Configure the datastore to be managed by a single vCenter Server system.
• C. Configure Storage DRS and then enable SIOC on the vCenter Server system.
• D. Enable Raw Device Mapping (RDM) on the ESXi hosts.

NEW QUESTION 15
An administrator is attempting to power on a virtual machine with 32GB of memory. The operation fails with the following error:
Could not power on VM: No space left on device
Checking the space on the virtual machine’s datastore, there is 30GB free. Which action would allow the VM to power on?

• A. Set a 2GB memory reservation on the VM.
• B. Mount the virtual disk from the affected VM on to another virtual machine and free up space from within the OS.
• C. Enable vSphere HD admission control on the cluster in which the VM resides.
• D. Set a 2GB memory limit on the VM.

Answer: A

Explanation: The swap file size can be calculated with the formula (.vswp File = Allocated Memory - Memory Reservation).
As per default, the reservation is set to 0, so the .vswp file size is equal to the amount of virtual memory.

NEW QUESTION 20
An administrator has an application that requires high CPU throughput. Which action would ensure that the application gets the required throughput?

• A. Enable Fault Tolerance on the virtual machine.
• B. Disable Fully Automated DRS.
• C. Set a CPU limit on the virtual machine.
• D. Adjust the virtual machine latency sensitivity.

Answer: D

Explanation: You can adjust the latency sensitivity of a virtual machine to optimize the scheduling delay for latency sensitive applications.
ESXi is optimized to deliver high throughput. You can optimize your virtual machine to meet the low latency requirement of latency sensitive applications. Examples of latency sensitive applications are VOIP or media player applications, or applications that require frequent access to the mouse or keyboard devices.
